For induction motors, parameters for the voltage emulation error cannot be determined with the
stationary motor data identification routine. When the system is commissioned for the first time
(p3900 = 3 or p0340 = 1 or 3), parameters p1952 to p1954 are preassigned so that the voltage
emulation errors can also be compensated for induction motors. The stationary motor data
identification routine provides more accurate values, so it should always be used for
synchronous motors.
Commissioning the function
The "Extended torque control" function module is activated offline. To commission the function
module, proceed as follows:
1. Click the drive and right-click to open the shortcut menu "Properties ... ".
The "Object Properties" window opens.
2. Click the "Function modules" tab.
The selection of possible function modules opens.
3. Click the "Extended torque control" checkbox to activate this option.
4. Click "OK" to activate the function module.
5. Select the "Connect to selected target devices" option.
6. Call the "Download project to target system" function.
Alternatively, you can also activate function modules in Startdrive under "Basic parameter
assignment > Function modules".
Activation can be checked in parameter r0108.1.
Activating the individual modules
To activate the individual modules, proceed as follows:
